New research projects in FISA http://www.fisaonline.de/ Here you will find the latest 20 projects that have been included in the Information System for Agriculture and Food Research (FISA). en-en Federal Office for Agriculture and Food TYPO3 Collaborative project: Measurement and balancing of material flows in agricultural systems with the purpose of reducing greenhouse gas emissions The purpose of the project is a fundamental expansion of knowledge about greenhouse gas emission, carbon fixation and carbon dynamic in agricultural crops. The results shall be used as a base to implement practical and location specific reduction strategies to prevent greenhouse gases. Therefor N2O-Emissions will be measured in continuous field experiments with high-definition and the processes of forming greenhouse gases (microbial processes, storage and decomposition of carbon) will be analyzed. The Measurements of N2O-flows will be used to observe the mechanism and influential factors for the N2O emergence. An essential innovation is the analyses of the soils N-dynamic and N2O-flows in dependence with C-decomposition processes. The N2O measurement data also serves for validating models. The long term analyses of humus dynamics and carbon quantities allow the derivation of coefficients of the humus reproduction for energy plants and digested residues. In field trials at the site in Trossin (Bavaria) practically relevant and site specific crops (maize, rape, winter rye, lucerne grass) will be evaluated. Drought resistant sorghum bicolor varieties will be evaluated in comparison with Maize regarding greenhouse gas emissions. Sorghum is for the region with warm and dry soils predestinated and therefore will be evaluated. Organic and mineral fertilizer variants and an intensive intermediate crop will be included in the evaluation. The cultivation systems will be analyzed in regard of their soil processes, yield potential, crop quality as well as environment-, climate- and resource efficiency. Long time effects of crop rotation and fertilizer systems that could not be quantified before will be analyzed. At the foundation of measurement data from own trials and experimental data from past trials material-, energy-, and greenhouse gas balances will be calculated.

Collaborative project: Modelling and measuring greenhouse gas emissions and nitrogen-leaching from raw material crop rotations The project MASTER aims to enhance the current state of knowledge regarding greenhouse gas emissions and soil carbon sequestration from raw material crop cultivation which is the basis for the development of site specific, praxis-oriented mitigation strategies. Within the project master, the subproject "Modelling and measuring greenhouse gas emissions and nitrogen-leaching from raw material crop rotations” will quantify long term greenhouse gas emissions and nitrate leaching using the biogeochemical model DNDC. The model will be used to simulate the addressed fluxes for German soil-climate regions and assess mitigation strategies for these regions. In a first step, the model will be calibrated on high resolution flux measurements from field experiments conducted in the project MASTER. Independent measurements will be used to validate the model. The in this way trained model will be used for extrapolations in space and time. Temporal extrapolations will allow investigating long-term effects of established raw material crop rotations on the interaction of greenhouse gas fluxes, soil carbon sequestration and nitrate leaching for the field experiments. The spatial extrapolation includes the modelling of mitigation scenarios in raw material crop rotations for soil-climate regions in Germany so that the interaction of natural conditions and mitigation strategies can be analysed which is an important improvement compared to TIER 1 approaches. Within the joint research project MASTER the Thünen Institute will analyse gas samples and quantify greenhouse gas fluxes from field experiments.

Collaborative project: Modelling and measuring greenhouse gas emissions and nitrogen-leaching from raw material crop rotations The aim of this project is to expand knowledge about greenhouse gas emissions, carbon sequestration and carbon dynamics in cropping systems for the production of raw materials, in order to derive realisable, site-specific mitigation strategies. To achieve this, N2O emissions will be measured with high temporal resolution in long-term field experiments, and greenhouse gas formation processes (microbial processes, carbon storage and degradation) will be analysed. In field trials at the Viehhausen (Bavaria) site, typical local crop rotations with the crops maize, oilseed rape, wheat and clover will be investigated. Organic and mineral fertilizers (biogas digestate, liquid manure, mineral N), treatments with different tillage methods and catch crop cultivation will be included in analyses. The cropping systems will be analysed with regards to their short- and long-term effects on soil fertility and soil processes, yield formation and product quality, as well as environmental, climate and resource efficiency. The measurement of N2O fluxes will elucidate mechanisms and factors influencing N2O formation. The as yet unquantified long-term effects of crop rotations and fertilization systems will be investigated. A key innovation is to link the analysis of the N-dynamics in soils and the N2O flows with C-turnover processes in soils. The N2O measurement data will also be used to validate our models. Analysis of long-term humus and carbon stock dynamics will enable the derivation of humus reproduction coefficients for energy crops and digestate. Nitrogen, humus, energy and greenhouse gas balances will be calculated based on measurement data from our own experiments and experimental data from previous experiments. Experimental data will be stored promptly and continuously in a project database in order to enable data analysis from all locations.

Collaborative project: Characterization of aboveground biomass and carbon storage in southern Bavarian forests by application of UAV-technology The main objective of the project with the title "Characterization of aboveground biomass and carbon storage in southern Bavarian forests by application of UAV-technology” is to quantify the aboveground biomass and carbon storage with UAV-technology (drones) in a cost-effective and timely manner. The study will be conducted on inventory points of the National Forest Inventory in Germany, located in the southern part of Bavaria (excluding points in the Alps). The flight campaign delivers efficiently information on the presence or absence of trees on inventory points. This information can be used in combination with modelling results for increment of growth, ingrowth, ongrowth and dead-wood-turnover to estimate carbon-storage in forests analogous to the way of the Federal State Ministry does. The study is accompanied by time studies which enables a monetary comparison of the UAV-approach with traditional forest inventory campaigns. The method also allows detecting changes in forest structures (tree species, stocks etc.) after disturbances.

Collaborative project: Small private forests: conservation through resource use, subproject 2: Social-ecological analyses The project aims to identify nature conservation values in small private forests against the background of an increased and further growing demand for raw wood and to secure these values within the framework of profitable forest management. In north-western Germany, those forest structures and characteristics of small private forests, which are valued by forest nature conservation, are to be identified on the levels of major natural regions and, in particular, model regions. Social-ecological studies analyse the targets and concrete management practices of small private forest owners as well as their views on problems and perspectives regarding nature conservation measures. For forestry practice, nature conservational-silvicultural decision aids are to be developed, which integrate measures that maintain the structures and habitats valued by nature conservation into profitable forest management. Exemplary economic analyses of nature conservational-silvicultural decision aids allow for the estimation of financial consequences. Innovative forestry policy instruments and mechanisms that aim at the promotion of forest nature conservation measures by the society are taken into account. The study results will be worked out in such a manner that they can be communicated to other regions with high proportions of small private forests.

Collaborative project: Detection and removal of pyrrolizidine alkaloid containing crop plants after harvesting, subproject 2: Development of a pneumatic driven selection of PA weeds out of medicinal and aromatic plants Targeted objective: Development of an efficient sorting solution for the separation of PA weeds out of fresh and dried plant fractions of tea. At the end of the project a sorting solution shall be presented, that demonstrates the separation of pure tea plants and contaminants on elected samples. In the light of today's knowledge, a hyperspectral NIR line scan camera will do the data acquisition within an optical sorting system. Separation of different product classes shall be done by compressed air. Work planning: Goal of the work is to reduce the share of weeds within the harvested elected medicinal and aromatic plants. Therefore fresh and dried plant fractions will be recorded by a hyperspectral line scan camera. Basing on different analytical methods, features of PA containing crops will be extracted. Result is a model description for registration and separation of PA crops. Finalizing work is the transfer of models to a demonstrator for a functionality check in practice. Exploitation of results: The project shall support reducing contamination of medicinal and aromatic plants with PA weeds before placing them into the market. The use of this scientific knowledge will bring producers of these products into the position to fulfill increasing legal requirements by using of optical sorting systems.

Collaborative project: Identification and reduction of pyrrolizidine alkaloid containing plants as contamination in herbal and medicinal plants by (hyperspectral) near-infrared spectroscopy The aim of this project is the development of a new, non-invasive analytical method for fast detection of pyrrolizidine alkaloid (PA) containing plant-derived contaminations in cultural plants, e.g. medicinal and aromatic plants. Such PA containing plants (i.e. comfrey, borage, echium, senecio ...) and parts of them should be detected by NIRS and hyperspectral NIR-imaging. Based on identification of characteristic spectral ranges and correlation analysis, appropriate discrimination models should be developed allowing the quantitative separation of target plants and PA contaminants. Furthermore, PLS models should be investigated allowing a quantitative estimation of the level of contamination both, in fresh and dried material. In the related partner project, multivariate statistics should be applied for reducing the corresponding large volume of data for developing an appropriate detection unit able to recognize contaminations on continuously moving flat-conveyers within few seconds. In combination with suitable separation unit this technique should be applicable for dried plants (herbal drugs) as well as fresh plant material.

Collaborative project: Development of a technological chain for the material utilization of hop plants - pre-project: technical feasibility For the first time, the scientific and technical prerequisites for the development of a technological chain for the material use of hop plants are to be determined and tested with the preliminary project. So far, after harvesting and stationary extraction of the cones (as value-giving plant components), the hop plants have either been left uncrushed or chopped, mainly in the fields, or abandoned to uncontrolled natural degradation. The hop vines, which can be up to 6 m long, represent a considerable biomass potential for material use that has not been exploited to date. In the preliminary project, the basic technical feasibility of selected technical utilisation routes for hop plants or stems and the intermediates obtained from them will be examined as examples. On the basis of this and an initial market assessment, it is planned to examine the favoured utilisation route(s) in more detail in a follow-up project and to work out the prerequisites for implementation on an industrial scale.

Collaborative project: Development of a technological chain for the material utilization of hop plants - pre-project: technical feasibility For the first time, the scientific and technical prerequisites for the development of a technological chain for the material use of hop plants are to be determined and tested with the preliminary project. So far, after harvesting and stationary extraction of the cones (as value-giving plant components), the hop plants have either been left uncrushed or chopped, mainly in the fields, or abandoned to uncontrolled natural degradation. The hop vines, which can be up to 6 m long, represent a considerable biomass potential for material use that has not been exploited to date. In the preliminary project, the basic technical feasibility of selected technical utilisation routes for hop plants or stems and the intermediates obtained from them will be examined as examples. On the basis of this and an initial market assessment, it is planned to examine the favoured utilisation route(s) in more detail in a follow-up project and to work out the prerequisites for implementation on an industrial scale.

Biomethane and peat substitute from poplar wood Poplar wood from short rotation plantations can be used as a renewable raw material for the production of renewable energies, e.g. for decentralized heat contracting. However, the use of climate-friendly wood heating systems in urban areas faces many challenges, such as the space required for heating systems and fuel storage, as well as the current discussion on fine dust. The use of poplar wood for biomethane production via the biogas process within the framework of this project is an innovative approach to the energetic use. The degree of innovation is further increased by the combination with the material use of the wood fibre fraction as a peat substitute after separation of the fermentation residues. The biogas process can be understood as an upstream conditioning step for the material use, which provides energy and exploits (with appropriate substrate conservation) the wood's potential of volatile substances too. The following tasks are addressed in the project: (1) Parameter identification (fibre length, fibre distribution) for a double-function disintegration treatment of poplar wood for biogas and peat substitute production, (2) Development of a process for the continuous, stable, and high-yield fermentation of poplar wood fibres to biogas (biomethane) on a laboratory scale, (3) Development and testing of crop cultivation utilisation concepts for the solid wood-fibrous fraction of the fermentation residues (tests as peat substitute) on a practical scale as well as theoretical considerations on the utilisation options of the liquid phase of the digestate, (4) economic and ecological evaluation of the overall concept (estimation).

Collaborative project: Complementary chemical-biotechnological process development for the novel production of 2,5-furandicarboxylic acid (FDCA) from inulin-accumulating plants - subproject 2: Inulin extraktion, Biocatalysis of FDCA In light of scarcity of fossil resources, plastics like polyesters and polyamides based on renewable resources are a promising alternative to conventional, oil-based polymers. Their potential is recognized by a growing number of plastic producers and entails appropriate R&D activities. A promising starting material for the production of bio-based polymers is 2,5-Furandicarboxylic acid (FDCA), which can be obtained from carbohydrates or carbohydrate-containing biomass, respectively. Polymers that can be made from it, like the polyester Polyethylene furanoate (PEF), are characterized not only by their sustainability, but also by improved properties, e. g. a reduced permeability for oxygen. The aim of the research project KEFIP is the development of a sustainable process for the conversion of inulin-containing chicory roots into FDCA. For that purpose, the inulin, being synthesised during growing and forcing, is firstly extracted, converted into 5-Hydroxymethylfurfural by the means of hydrothermal dehydration and finally oxidized to FDCA by bio- and heterogeneous catalysts, respectively. For the purposes of a resource efficient process, HMF originating from the hydrothermal dehydration shall not be extracted and purified, but used directly for oxidation. Fraunhofer IGB is focussing on the extraction of inulin from chicory root beets. In addition to conventional hot water extraction, the concurrent use of inulinases increasing the yield and release of fructose is also evaluated. On the other hand Fraunhofer IGB is working on the biocatalytic conversion of HMF to FDCA. First, an evaluation of the potential of enzymatic conversion versus whole cell catalytic conversion is carried out. A subsequent optimization of the selected method mainly concerns the process engineering.
